Abstract

There is disclosed an on-board navigation terminal, comprises received data storing means for storing received data concerning a navigating application received from a center system, based on a profile transmitted to the center system through communicating means; and navigating application available data generating means for generating available data based on map data stored in map data storing means, and the received data stored in the received data storing means.

Claims

1. An on-board navigation terminal comprising:

map data storing means for storing map data;

communicating means for performing communications with an external navigation controller;

received data storing means for storing received data containing relevant information concerning an application for transmission transmitted from said navigation controller and received through said communicating means, based on unique information transmitted through said communicating means to said navigation controller; and

data generating means for generating available data based on the map data stored in said map data storing means and the received data stored in said received data storing means.

2. An on-board navigation terminal according to claim 1, further comprising unique information recording-reproducing means for recording or reproducing unique information specifying a content of the relevant information transmitted from the navigation controller.

3. An on-board navigation terminal according to claim 2, further comprising unique information recording-changing means for changing the unique information recorded by said unique information recording-reproducing means depending on what kind of change is made therein.

4. An on-board navigation terminal according to claim 2, further comprising automatic unique information updating means for automatically updating the unique information recorded by said unique information recording-reproducing means.

5. An on-board navigation terminal comprising:

map data storing means for storing map data;

communicating means for performing communications with an external navigation controller;

identification information recording-reproducing means for recording or reproducing identification information for identifying unique information recorded or reproduced by unique information recording-reproducing means provided in the navigation controller;

received data storing means for receiving data from the navigation controller, containing relevant information concerning a content specified by the unique information which is identified based on the identification information reproduced by said identification information recording-reproducing means and transmitted through communicating means to the navigation controller, and for storing the received data; and

data generating means for generating available data based on the map data stored in said map data storing means, and the received data stored in said received data storing means.

6. An on-board navigation terminal according to claim 5, wherein said received data storing means stores received data containing, as relevant information, difference information indicative of a difference between a conventional map and a newly changed latest map.

7. An on-board navigation terminal according to claim 5, wherein said received data storing means stores received data containing specific relevant information corresponding to the unique information.

8. An on-board navigation terminal according to claim 5, wherein said received data storing means stores received data containing, as relevant information, additional information added to a navigating application.

9. An on-board navigation terminal according to claim 5, further comprising charging means for receiving or transmitting charging information concerning a service rendered from the navigation controller through said communicating means.

10. An on-board navigation terminal according to claim 9, wherein said charging means is provided with prepaid card driving means for driving a loaded prepaid card.

11. A navigation controller comprising:

communicating means for performing communications with an external on-board navigation terminal;

transmission data storing means for storing a plurality of transmission data containing a plurality of relevant information concerning a navigating application utilized in the on-board navigation terminal; and

transmission data determining means for determining transmission data containing relevant information having a content corresponding to unique information, among the plurality of transmission data stored in said transmission data storing means, when the unique information or identification information specifying the unique data is received through said communicating means from the on-board navigation terminal, and for transmitting the determined transmission data to the on-board navigation terminal through the communicating means.

12. A navigation controller according to claim 11, further comprising unique information recording-reproducing means for recording or reproducing the unique information specifying the content of the relevant information.

13. A navigation controller according to claim 12, further comprising unique information recording-changing means for changing the unique information recorded by said unique information recording-reproducing means depending on what kind of change is made therein.

14. A navigation controller according to claim 12, further comprising change detecting means for detecting information changed with an elapse of time in the on-board navigation terminal side at every fixed time;

and automatic unique information updating means for automatically updating the unique information recorded by said unique information recording-reproducing means depending on the change detected by said change detecting means.

15. A navigation controller according to claim 11, wherein said transmission data storing means stores transmission data containing, as relevant information, difference information indicative of a difference between a conventional map and a newly changed latest map.

16. A navigation controller according to claim 11, wherein said transmission data storing means stores transmission data containing specific relevant information corresponding to the unique information.

17. A navigation controller according to claim 11, wherein said transmission data storing means stores transmission data containing, as relevant information, additional information added to the navigating application.

18. A navigation controller according to claim 11, further comprising charging means for transmitting or receiving charging information concerning a service rendered to the on-board navigation terminal through said communicating means.

19. A navigation controller according to claim 18, wherein said charging means does not make a charge till a predetermined condition is met from a start of the service rendered to the on-board navigation terminal.
